推荐答案

试试这个

Try this

string str = "this is a #string";
string ext = str.Substring(0, str.LastIndexOf("#") + 1);

这应该有效。根据你的需要调整它。

THis should work. tweak it as pr your needs.

一旦我认为它适用于你，我会检查这个。

Hi check this once I think it works for u

string str = "asd.uk";
            if (str.Contains('.'))
            {
                int index = str.IndexOf('.');
                string result = str.Substring(0, index);
                Console.WriteLine("result: " + result);
            }
